t DEYIiCE EGR ITE/EATING SvELTEH-FUMES.

To ZZ whom' it may concern .V .I A i y* Be it known that .1',"0Ilor' V. Bron, a `citizen of the United' States, residing at. Fresu@1 in thecountyo Fresno, State of California, .have'fnvented certain new rand luseful rnprovements in af Device, for Treating Snielter-Eumes ;a.nd do declarev the follow# 'ing' to be a full, clear, and exact description of the sangleJ such -as Will enable others skilled in the art towhich it appertains to make and use the same7 reference being hady lin afmechanism for treating the funieslof smelters used ,for roastingr and smelting ores,

'the ohject ofthe invention being' to produce a means whereby the deleterious material in such fumes may be precipitated prior to the fumes 'escaping tothe atmosphere for the purpose o'f removing' such deleterious elementsin 4order that they not spread and do damage to the property surrounds ing the smelten. is is a "Well known tact, the deleterious elements ofthese fumes are 110W extremely injurious to trees and vege- 'tation and in fact all kinds of property surrounding thev smelter and :this has resulted in a great many of the smelters being 'enjoined roni', operation. The object "of my invention is to overcome all of these diliiv cultiesD y A further object of the invention is 'to produce a simple and inexpensive device and yet one which will he exceedinglyI effective tor the purposes for-which it is designed.

lThese objects, accomplish byinieanso such struct-ure and relative arrangement ot' the parts as willfully appear by perusal of the following' specication and dlaini.

The figure ot the drawingsis a side ,ele-

, .vation, partly in section, of a' portion of my improved mechanism.

Referring now lmore particularly Vto the characters of reference on the dra-wings, the numeral 1 designates the furnace provided with suitable burners and out-lets of any desired type and hence no specific description of the same is here entered into. in addition to this, I provide a system of auxiliary oil and compressed air inlets 2 adapted to assist in the consumption of the products delivered to said uraiace l. ,x

In applying; my' improved striictiire, preferab y dispose the same on a hillside Spectcation of Letters Ea tent.

or in an inclined manner and the same consists ot a tine or outlet 3 arranged in steps, each stop beingprovided at its junction with an adjacent step with an inclined receiving and delivering hox having a door 5 adaptedto deliver into a. trough 6. At each junction of each adjacent pair of said steps I provide a spray nozzle 7 connected by pipes 8 with Water tanks 9. Then as the fumes from the urnace'i. pass through the varions steps they are subjected to a Water or other solution spray and such of the elements thereof as are susceptible of precipitation are precipitated and then these 'precipitated elements will drop into the receiving; and delivering box 4 from whence they' mayv pa ss into trough 6. The overflow Water from the members 4 inay he drained through pipes ha into the next lower Watertanl; 9.

rlfhe arrangement of the structure into steps is; so as to place the chutes 4e under their adjacent upper steps so that the elements precipitated by the water spray at that point Will,readily fall into the chutes. instead of 'the Water spray used compressed air may he admitted through 'a pipe 10 or other similar elements maybe admitted to tite vspray member Y, lwhich elements are 'ltd'undvadaptable for precipitating certain of thfe elements in the fumes. y All of theoperationsof the device will of course 'depend upon the character of the 'fumes heing treated and the necessary solutions and other elementsnecessary totheir precipihationD the especial pointoi2 the invention being,l the stepped structure and in admitting. the precipitatiugr elementa-t the `iunction of each step, 'with the receiving,I

chute below each step to receive the precipitated elements. p k y To prevent any oit the fum/is escaping .when the Jfurnace is being' charged. I provide a series of control gates, which structure is as,tollows,'naincly: r.Ehe numeral ll indicates a receiving;` gate opening'into a chamber l2 which has a ,frate 13 opening into another chamber lll communicating at 15 with the lue structure This chamber la has a gate i6 communicotinay with the furnace l. rhe charge of ore 17 is irst emptied through the grate il into the chamber i2. lThe gate ll is then closed and the gate 3 3 opened` The `gate 13 is then Yclosed and the fate 1G opened which admits the. charge ot the furnace L any fumes escaping therefrom passing through the chamber 14: and

opening 15 into the flue structure 3. The initial chamber 12 is'always closed when the chamber-14 is opened and thus this prevents any escape ofthe fumes to the atmosplie-re when the furnace is being charged.

From the foregoin r description it will be readily seen that 'I inve reduced such a device as substantial] 4fulfils the objects of the invention as set orth herein.

While this specification sets forth in de tail the present and preferred construction of the device, still in practice such deviations fromk such detail may be resorted to as do not form a departure from the spirit of the invention.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent isz- A conduit for use in treatingr srnelter .fumes, the same comprising an inclined con @uit arranged in steps a rece tacle openin into said conduit 'ust below t e juncture o adjacent steps and disposed at substantially right angles to said conduit whereby the bottom o cinch receptacle inclines toward its lower corner, u door in the lower corner of each receptacle, another receptacle disposed below each of said first named receptacles, and a pipe lending from the upper side of one end of each of said first named receptacles to the corres ending receptacle below the same2 as described.

In testimon whereof I affix my signature in presence o two witnesses.
